How to read the XTE scale
The black boat-shaped mark shows own
boat’s movement and direction, and amount
to steer to return to course. Using Figure 3-
13 as an example, you would steer right by
000.02 nautical miles to return to course.
When this mark is out of range of the XTE
scale, the mark color changes from black to
yellow. The range of the XTE scale can be
set as shown below (default: 0.5 nm).

sentation of ship’s track along intended

XTE scale shows direction and amount in
nautical miles to steer to return to course. In
the figure below, for example, you would steer
right by 0.02 nm to return to course.
Press the [PLOT] key once or twice to show
the highway display.
